Updated April 2026 Official HMRC rates First‑time buyer focus

Introduction: buying a home in 2026

The UK property market in 2026 continues to evolve with stabilising interest rates and stamp duty thresholds that reflect post‑pandemic adjustments. Whether you're a first‑time buyer, moving home, or purchasing an additional property, understanding both mortgage options and Stamp Duty Land Tax (SDLT) is crucial. This guide combines the latest 2026 data with practical steps to help you budget and save.

Stamp Duty Land Tax (SDLT) – 2026 rates

SDLT is a tax you pay when buying a property or land over a certain price in England and Northern Ireland. (Scotland and Wales have different systems – LBBT and LTT.) The table below shows the residential SDLT rates for 2026 (effective from April 2025, with no major changes announced for 2026).

Purchase price (portion)Standard rate
Up to £250,0000%
£250,001 – £925,0005%
£925,001 – £1.5 million10%
Over £1.5 million12%

Note: The 0% band was previously £425,000 for first‑time buyers – see below.

🏡 First‑time buyer relief (2026)

If you and everyone else purchasing is a first‑time buyer, you can claim relief on properties up to £625,000. You pay:

➕ Additional property surcharge

Buying a second home or buy‑to‑let? An extra 3% is added to each SDLT band. Companies and trusts may pay even higher rates.

Example 2026 calculation: A first‑time buyer purchases a £500,000 flat. SDLT = 0% on first £425,000 + 5% on remaining £75,000 = £3,750. Without relief, the tax would be 0% on first £250k + 5% on £250k = £12,500. Saving: £8,750.

Mortgage essentials for 2026

Most buyers need a mortgage – a loan secured against the property. Key terms: loan‑to‑value (LTV), term, fixed or variable rate. In 2026, average 2‑year fixed rates hover around 4.5%–5.5%, but they vary by lender and deposit.

Main mortgage types

How much can you borrow?

Lenders typically offer 4–4.5 times your annual household income. Some go up to 5.5x for high earners or with large deposits. Affordability checks also consider your outgoings, credit score, and stress tests (interest rate +3% typically).

Affordability & budgeting tips for 2026

Deposit size

Aim for at least 10% LTV to access best rates. 5% mortgages exist (guarantee schemes), but rates are higher.

Agreement in Principle

Get an AiP before house hunting – shows sellers you're serious and confirms your budget.

Term length

Longer term (30‑35 years) lowers monthly payments but increases total interest.

Additional costs to factor

2026 tip: With rates more stable than in 2023‑24, consider a 5‑year fix if you plan to stay longer. Use a mortgage calculator to compare total costs.
